These percentages only report the utilization of the hardware. Current utilization is not necessarily
indicative of how long your jobs may wait to run.

Some jobs are preemptable and may be evicted the moment you submit new jobs. Others jobs
may be nearing completion and you might only have to wait a few minutes. Or maybe
the queue is so long and your priority so low that you'll wait for days.

The only way to know is to examine the queue or just submit your jobs. Don't assume that
100% utilization means "I might as well give up" because that is very likely incorrect.
Submit your jobs and hope for the best.
